If you suspect PCB - try it, but you would need to transfer ROM.

Is there a way to find out what exactly is wrong with my drive and then decide to have it fixed or toss away?

How to determine if the heads have not gone bad?

Please share you thoughts and expertise.

Now if your drive is working go and copy quick all the data you can and if not throw it out tho the garbage or send it to the manufacturer.

Shorting read channels:
short the pins shown here
Code:

this is the component side, it goes through the pcb to the other side, I think here
Code:

but not sure - thrust the first image its 100% ok



Thanks everyone. I fixed my ST31000528AS 1TB Barracuda 7200.12 Firmware: CC49 model hdd with help of that and with another command.
At first I have to say my aim for fixing it was to USE it. Not for data recovery but it was surprising when I saw 2. and 3. partitions (with files in them) on my hdd were't deleted after my fix. I used soldering,may be you don't have to but if you will then it is your own risk.
My mobo couldn't see hdd in bios or hot swap. It was after a low voltage and psu failure.
I tried a lot of things but always got an error
Quote:
Rst 0x20M
Servo Processor Is Reset.
RW: Disc Ctlr Initialization Completed.

ExecuteSpinRequest

(P) SATA Reset

Then I looked at connections on the PCB and measered the diots with a cheap and simple multimeter and found these diodes on SATA DATA connection are not working. I soldered them to disable / by-pass them. After soldering; data flows from SATA port to PCB like there is no diode. Don't solder any diode with another one.
Code:
http://img427.yukle.tc/images/3649Clipboard02.jpg

Code:
http://img429.yukle.tc/images/5606Clipboard03.jpg
You can see 3 other diodes next to the ones that I marked. They were running OK in my hdd but if not in yours, you can solder them.
Then I tried the commands with the help of a DKU-5 cable. But I got "Inıt SMART fail" errors and I did like that:
Code:
[Power your hdd with shorting read channels as R0b and bochen415 says like in that image: http://qbhn.neostrada.pl/02.jpg]

After that I removed DKU-5 cable connections and atteched hdd to computer and restart. It was visible on BIOS and windows saw hdd with all partitions. I tried seagate tools -both windows and dos but couldn't full erase disk to fix bad sectors. I am running hdtune and erasing it, if that won't work, I will learn where bad sectors are with its Error Scan and setup a couple of partitions to use hdd.
good luck.

Dysk,

You will not be able to reply to my PM as you have not accumulated enough posts to have PM-ing privilege.

I can't help without providing some history about the drive, behavior prior to and after failure, do you have the tools you need, what tests have you run and what were the results? Have you issued any commands already (I am NOT suggesting to do so)? If yes, which commands exactly? Etc.

Read the thread from beginning to end and give proper details.

Wouldn't it be dangerouse to use the same procedure for a 7200.11 drive on a 7200.12 drive die to the Non-Resident G-List issue ?

Not always, it's danger only if NRG is filled with some entries, if is empty it's ok to regen translators (m0,2,2,,,,,22).
You may check if NRG is empty with V40 command.

I've got a 7200.12 HD with partial accesibility problem (almost total) 99% bad sectors. I regen translators and the NRG list wasn't empty :oops:
The beginning of the bad sectors match with the first entry in the NRG list.
Data isn't very important, just for try... how could I delete the NRG list?

Thanks!

Can anybody help me with almost same problem:

In terminal I got response from disk:

Rst 0x20M
No HOST FIS-ReadyStatusFlags 2002B001
ASCII Diag mode

I have tried to proceed SMART data cleaning same way as for 7200.11, but no success on step F3 1> N1... Disk gives back infinite "LED:000000CC FAddr:0024E2DB...."

As I see here 7200.12 has to have other sequence.
Help, please, 10 years archive of photos can be stolen, disk stopped to be recognized by BIOS

If you want to ship the drive to Portugal i don't mind to have a go at it and try to fix the NRG with the FORK method and extract data with DE after stoping relocation with cogen.
I will charge a reasonable fee way cheaper then a conventional data recovery firm.
PM if interested.
